Embodiment 1

[0044] An antibacterial and mildew-proof polyethylene composite plastic masterbatch, the raw materials and mass percentages of the plastic masterbatch are: 1% titanium dioxide composite antibacterial agent, 5% silicone oil, 2.5% titanate, and 91.5% polyethylene plastic; Among them, the raw materials and parts by weight of the antibacterial liquid used to prepare the titanium dioxide composite antibacterial agent are: 13 parts of fresh fennel seedlings, 14 parts of fresh purslane, 10 parts of fresh camphor leaves, 7 parts of cinnamon, and Imperata rhizome 5 parts, 6 parts of Angelica dahurica, 7 parts of Coptis chinensis, 2 parts of Fructus Cnidii, 9 parts of Folium Folium, 4 parts of roasted licorice.

[0045] The crude drug of described antibacterial liquid medicine is made by following steps:

[0046] a) Cinnamon, Rhizoma Imperatae, Angelica dahurica, Coptis chinensis, Fructus Cnidii, Folium Folium, and Radix Glycyrrhizae are mixed and washed, then crushed to 100 mesh powder...

Embodiment 2

[0052] An antibacterial and mildew-proof polyethylene composite plastic masterbatch. The raw materials and mass percentages of the plastic masterbatch are: 0.8% titanium dioxide composite antibacterial agent, 4% silicone oil, 2% titanate, and 93.2% polyethylene plastic; Among them, the raw materials and parts by weight of the antibacterial liquid used to prepare the titanium dioxide composite antibacterial agent are: 12 parts of fresh fennel seedlings, 12 parts of fresh purslane, 8 parts of fresh camphor leaves, 6 parts of cinnamon, and Imperata rhizome 4 parts, 5 parts of Angelica dahurica, 6 parts of Coptis rhizome, 1 part of Fructus Cnidii, 8 parts of Folium Folium, 3 parts of Radix Glycyrrhiza; According to the standard test in the industry, the results are as follows: the 24-hour sterilization rate of Escherichia coli reaches 98.8%; the 24-hour sterilization rate of Staphylococcus aureus reaches 99%.

Embodiment 3

[0054] An antibacterial and mildew-proof polyethylene composite plastic masterbatch. The raw materials and mass percentages of the plastic masterbatch are: 1.2% titanium dioxide composite antibacterial agent, 6% silicone oil, 3% titanate, and 89.8% polyethylene plastic; Among them, the raw materials and parts by weight of the antibacterial liquid used to prepare the titanium dioxide composite antibacterial agent are: 15 parts of fresh fennel seedlings, 15 parts of fresh purslane, 12 parts of fresh camphor leaves, 9 parts of cinnamon, and Imperata rhizome 6 parts, 7 parts of Angelica dahurica, 9 parts of Coptidis Rhizoma, 3 parts of Fructus Cnidii, 10 parts of Folium Folium, 5 parts of Radix Glycyrrhizae; According to the standard test in the industry, the results are as follows: the 24-hour sterilization rate of Escherichia coli reaches 99.2%; the 24-hour sterilization rate of Staphylococcus aureus reaches 99.5%.

Abstract

The invention discloses an antibacterial and mould-proof polyethylene compound plastic masterbatch. The plastic masterbatch is prepared from a titanium dioxide compound antibacterial agent; the titanium dioxide compound antibacterial agent is prepared by carbonizing electrospun enteromorpha nano-particles / titanium dioxide fibers, carrying out acid-washing, soaking in antibacterial liquid, drying and grinding into micro / nano-particles, wherein the antibacterial liquid is extracting liquid of a traditional Chinese medicine antibacterial component. The material has very good antibacterial property, and can effectively inhibit the propagation of microorganisms such as bacteria and mould on the surface of the material, so as to achieve the effects of resisting bacteria and preventing mould and maintain self cleanness.

Description

technical field [0001] The invention relates to a plastic material, in particular to an antibacterial and mildew-proof polyethylene composite plastic masterbatch. Background technique [0002] Antibacterial plastics are a type of plastics that can inhibit or kill bacteria, molds, alcohol mothers, algae and even viruses that are stained on plastics in the use environment, and keep themselves clean by inhibiting the reproduction of microorganisms. After being applied in home appliances and daily necessities, antibacterial plastics will be increasingly used in building materials and interior decoration materials. More and more antibacterial materials will be used in the interior of high-end cars. For example, the steering wheel, interior flannel, seats, handles, etc. of Nissan cars have been made of antibacterial plastics and antibacterial materials. Polyethylene (PE) is a widely used plastic material, which can be processed by blow molding, extrusion, injection molding and ot...
